slvnvruncgvtest

Invoke Code Generation Verification (CGV) API and execute model

collapse all in page

Syntax

cgvObject = slvnvruncgvtest(model, dataFile)
cgvObject = slvnvruncgvtest(model, dataFile, runOpts)

Description

cgvObject = slvnvruncgvtest(model, dataFile) invokes the Code Generation Verification (CGV) API methods and executes the model by using all test cases in dataFile. cgvObject is a cgv.CGV object that slvnvruncgvtest creates during the execution of the model. slvnvruncgvtest sets the execution mode for cgvObject to'sim' by default.

example

cgvObject = slvnvruncgvtest(model, dataFile, runOpts) invokes CGV API methods and executes the model by using test cases in dataFile. runOpts defines the options for executing the test cases. The settings in runOpts determine the configuration of cgvObject.

Examples

This example shows how to log signals, run tests, and compare results for generated code using the code generation API.

Open the directory that contains the example files.

openExample('ComponentBasedModelingWithModelReferenceExample')

Open the sldemo_mdlref_basic example model and log the input signals to the CounterA model block.

open_system('sldemo_mdlref_basic');
load_system('sldemo_mdlref_counter');
loggedData = slvnvlogsignals('sldemo_mdlref_basic/CounterA');

Create the default configuration object for slvnvruncgvtest and allow the model to be configured to execute test cases with the CGV API.

runOpts = slvnvruntestopts('cgv');
runOpts.allowCopyModel = true;

Execute the test using the logged signals first in normal mode, and then in software-in-the-loop (SIL) mode.

cgvObjectSim = slvnvruncgvtest('sldemo_mdlref_counter', loggedData, runOpts);
runOpts.cgvConn = 'sil';
cgvObjectSil = slvnvruncgvtest('sldemo_mdlref_counter', loggedData, runOpts);

Compare the results of the first test case.

simout = cgvObjectSim.getOutputData(1);
silout = cgvObjectSil.getOutputData(1);
[matchNames, ~, mismatchNames, ~ ] = cgv.CGV.compare(simout, silout);
fprintf('\nTest Case:  %d Signals match, %d Signals mismatch', ...
        length(matchNames), length(mismatchNames));

Input Arguments

collapse all

Name of the Simulink® model that you execute.

Name of the data file or a structure that contains the input data. Generate data by either:

  • Using the Simulink Design Verifier™ software to analyze the model.

  • Using the slvnvlogsignals function.

The fields of runOpts specify the configuration of slvnvruncgvtest .

Field NameDescription
testIdx

Test case index array to simulate from dataFile.

If testIdx = [] (the default), slvnvruncgvtest simulates all test cases.

allowCopyModel

If you have not configured your model to execute test cases with the CGV API, this field specifies creating and configuring the model.

If true and you have not configured your model to execute test cases with the CGV API, slvnvruncgvtest copies the model, fixes the configuration, and executes the test cases on the copied model.

If false (the default), an error occurs if the tests cannot execute with the CGV API.

Note

If you have not configured the top-level model or any referenced models to execute test cases, slvnvruncgvtest does not copy the model, even if allowCopyModel is true. An error occurs.

cgvCompType

Defines the software-in-the-loop (SIL) or processor-in-the-loop (PIL) approach for CGV:

  • 'topmodel' (default)

  • 'modelblock'

cgvConn

Specifies mode of execution for CGV:

  • 'sim' (default)

  • 'sil'

  • 'pil'

Note

runOpts = slvnvruntestopts('cgv') returns a runOpts structure with the default values for each field.

Output Arguments

collapse all

cgv.CGV (Embedded Coder) object that slvnvruncgvtest creates during the execution of model.

slvnvruncgvtest saves the following data for each test case executed in an array of Simulink.SimulationOutput objects inside cgvObject.

Field

Description

tout_slvnvruncgvtest

Simulation time

xout_slvnvruncgvtest

State data

yout_slvnvruncgvtest

Output signal data

logsout_slvnvruncgvtest

Signal logging data for:

  • Signals connected to outports

  • Signals that are configured for logging data on the model

Tips

To run slvnvruncgvtest, you must have the Embedded Coder® software.

If your model has parameters that are not configured for executing test cases with the CGV API, slvnvruncgvtest reports warnings about the invalid parameters. If you see these warnings, do one of the following:

  • Modify the invalid parameters and rerun slvnvruncgvtest.

  • Set allowCopyModel in runOpts to be true and rerun slvnvruncgvtest. slvnvruncgvtest makes a copy of your model configured for executing test cases, and invokes the CGV API.
